Recently the X-parameter paradigm has been introduced. The formalism provides a comprehensive description of the relationships between all the harmonics of the scattered and incident power waves at the ports of a device, and represents a major advancement in RF circuit characterization. The formalism however still needs effective handling of the long term memory effects. In this paper, a simple and efficient approach is proposed to model long-term memory effects within X-parameter. It ensures both a simple extraction procedure and an efficient numerical implementation.","PeriodicalId":6385,"journal":{"name":"2012 IEEE/MTT-S International Microwave Symposium Digest","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75786572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If these resonators are symmetrically etched in the back substrate side of the CPW, the resonators are not excited, and signal propagation along the CPW is allowed. Conversely, if the symmetry is truncated, the magnetic wall of the CPW (fundamental mode) is not aligned with the electric wall of the resonator, and signal propagation is inhibited in the vicinity of the first resonance frequency. These structures can be of interest for the design of novel sensors or radiofrequency (RF) bar codes, based on the deviation from symmetry. The principle of operation of such structures is illustrated and experimentally validated by proof-of-concept devices.","PeriodicalId":6385,"journal":{"name":"2012 IEEE/MTT-S International Microwave Symposium Digest","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72790140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, CMOS implementations of two novel analogue beamforming multi-channel receivers will be presented. A narrow-band highly linear system exploiting switches and capacitors in advanced CMOS is presented, implementing a fully passive switched capacitor vector modulator exploiting a zero-IF I/Q mixer: This technique is not applicable to very wideband phased-array receivers. These systems require true-time delay beamforming, which is implemented in the second CMOS implementation. An innovative gm-RC implementation of a true-time delay cell is exploited in a four-channel beamforming receiver with more than 1.5 GHz bandwidth, in a standard 0.13 um CMOS process. Professional phased-arrays can often not live with the dynamic range limitations imposed by these implementations. To that end a SiGe implementation of an integrated receiver was realized targeting a digital beamforming phased-array. Dynamic range and flexibility of use were the main driving factors. Alltogether, these results show large progress with respect to the feasibility of Silicon-based phased-array front-end implementation for commercial as well as professional phased-arrays.","PeriodicalId":6385,"journal":{"name":"2012 IEEE/MTT-S International Microwave Symposium Digest","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84251067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
